SPECIFICATION forming part of Letters Patent No. 356,599, dated January 25, 1887.

l Application tiled December 3, i885. Serial No. 184,553. (No model.)

To a-.Zi whom, t may con-cern.-

Be it known that I, ROBERT XV. PAIN, of.

'Io are propelled by motors operated by Wind produced through the action of bellows or analogens contrivances.

The object of my improvement is to produce i'or such an instrument a motor simple in construction, powerful in action, and compara tively noiseless.

I will describe a motor embodying my improvement and such parts of a musical instrument in which it is to be uscd as may be necessary to a thorough understanding of the motor, and then I will point out the various features of my improvement in claims.

In the accompanying drawings, Figure l is a vertical section ot' mechanical musical in E 5 strument embodying the improvement, certain parts, which are immaterial so far as my improvement is concerned, being omitted. Fig. 2 is a top view of a motor which is comprised in said instrument. Fig. 3 is a transverse 3o vertical section of the motor, taken at the plane of the dotted line .fa-Fig. 2. Fig. 4 is a transverse vertical section of a motor modified in form.

Similar letters of reference designate correspending parts in all the figures.

A designates the bellows of the musical instrument. Any suitable number of them may be employed, and they may be of ordinary construction. In the present example of my .to improvement they are represented as being of the kind known as suction-bellows. They may be operated'in any appropriate man ner,-

as, for instance, by means of a treadle connected with them through the agency of a pitman, A. The bellows communicate with au equalizer, B, which is of similar construction to the bellows. The equalizer communicates by means of a trunk, B", with a Windchest, N. In this vrind-chest are pneumatic motors I?,

5o which serve to operate levers L,provided With valves L,whereby the operation of the soundproducing devices is controlled.

The pneumatic motors P connect with ducts in a rest, It, over .which passes a traveling music-sheet, S, which is perforated and controls the passage of air through the ducts to the pneumatic motors, and consequently controls the speaking of the sound-producing devices in order to produce tunes.

The music-sheet is fastened at one end to a 6o roller, O, and at the other end to a roller, C.

It is unrolled from the roller C to the roller O in order to produce a tune, and afterward it is rolled hack from the roller O onto the roller C', it being kept normally Wound upon the 65 latter. The roller O is consequently termed a music-roller. Itis arranged in open bearings, so that it may be taken away and be replaced by another. rIhe roller C is usually termed the takenp roller.

The sound-producing devices which I have shown consist of reeds which are arranged in cells communicating with the Wind-chest under control of the valves L.

The rollers C O are operated by the motor to which I have previously referred. This motor has a main shaft, D, on which are fixed pulleys D D2, of di'erent sizes. The pulley D connects through a crossed belt, I, with a pulley, C2, on a shaft, 0*, that transmits motion to the roller C. rIhe pulley D receives a belt, G, that is passed around a pulley, C3, on a shaft that engages with the roller C.

Mechanism is provided whereby the shaft O4 may be disengaged temporarily from the 85 roller C, and the shaft- O may be disengaged from the roller C. This mechanism is to operate so that When either roller is engaged With its shaft the-other roller will be disengaged from the shaft which is employed to transmit motion to it. As this mechanism does not form part of my present improvement, I have not illustrated it.

My improvement comprises a number of bellows-like chambers or pneumatics, F F F3. 95 I have only shown it in Fig. 2 as having three such chambers; but the number may be increased. 'Ihese chambers consist oi stationary boards j, movable boards f, which are adapted to have a swinging motion, like the 10c 9 slasee i movable boards of ordinary bellows, andy dexible connections f 1between the boards, consisting of india-rubber cloth or like material.`

These chambers, as shown in Fig. 2,are arranged side by side in a line. Their stationary boards are tixedto a block or case, E, that has air-passages e e2 c extending vertically through it, and passages e" e5 cG extending-horizontally from the passages c e2 e to holes in the stationary boa-rds f of the chambers F F2 F, and thus communicating with the interior of these chambers. The passages c e2 e communicate with a trunk, E', which, as here shown, is arranged immediately below the block E, and communicates, by means of suit# able conduits, IIl, with the equalizer B. The

block E has arranged above it valves V W V8v and below it valves IV. One pair of valves is employed for each of the passages e c2 e". The valves V Vz V3 control the communication between the upper ends of the passages e e e3 and theatmosphere. The valves NV control communication between the lower ends of said passages and the wind-chest. Although I may use any suitable kind of valves, I prefer to make these valves of strips of wood faced with sheep-skin or similar material, and secured in place at one end by hinges consisting of like tiexible material. The valves of eaclrpair are connected by rods which pass through the passages e e2 c3 and extend considerably above the block E. The `valves V W are connected by a rod, U, andthe valves V2 W are connected by a rod, U2, and the valves 'V3 IV are con-- nected by a rod, U3.

The shaft D is provided with cranks d d2 d3, which are set at different angles at about corresponding distances apart circumferentially of the circle in which they revolve. They are connected, by pitmen DI BIZ M, with projections from the movable boards f of the chambers F FZ F3. Cams K E Il are fixed to the shaft D. Their operative faces occupy differient positions circumferential] y of the shaft, in order that they may impart motion to the valves V V2 V5 INV, controlling the chambers F F2 F3 at different times.

Levers G Grl G, fulcrumed at one end to xed supports, and connected at the other end to the rods U U2 U3, extend over the cams K V'K2 K3, so' as to derive motion from the latter and impart it, through the rods U U2 U3, tov

n the valvesVV2 VVW.

Vvhenever a valve V or V2 or V3 is closed `upon its seat and the corresponding valveV, is opened, the chamber F F" F3 controlled by such pair of valves will be in communication with the equalizer' B, and the atmospheric pressure upon its movable board` will cause the latter to swing into proximity with the xed board. The force with which thev movable board swings inward is transmitted to the shaft D. Vhen the pair of valves is reversed, the chamber will be put in communication with the atmosphere, and by the rotation of the shaft D the movable board of such chamber will be swung to its outermost po- ,board f.

sition again.` Thechambers all operate in this way at different times, so as to successively act upon the shaft D1.

Preferably the levers G. Gr2 G3 haveinot a rigid connection with the i rods U U2 U3, but are slotted to embrace the rods, and have springs interposed between them and heads which are iixed to the rods. Thus any undue strain on the valves will be obviated.

Obviously the motor which I have described could be operated through the agency of forcebellows instead of suction-bellows. Then the pressure ot air inside `the chambers would force the movable boards of the chambers outward to impart motion to the shaft. No modi.-

fication of the motor would be necessary for it to .operate in conjunction with force-bellows.

In the example of motor previously described each of thecollapsible chambers F', F2, or F3 is single acting. In otherwords, each chamber exerts power upon the shaft D only while the movable board, and consequently the pitman connecting the movable `board with the said shaft, moves in one direction.

In Fig. 4; I have illustrated a modified form of motor which has double-acting chambers F; Any suitable number of these double-acting chambers may beemployed. There should, however,be at least twoof them. Each cham` ber has two fixed boards, f, and any interme-` diateswingingboard, f. Thisswingingboard` f is hinged at the lower `edge to the bottom of the chamber.

nected with the bottom of the chamber, the fixed boards f thereof, and the swinging The `swinging board is arranged midway between the two fixed boards of the chamber and divides the chamber into two compartments. Vhen it swings in one direction, it collapses or reduces the comparta l ment which is formed between it andthe fixed i board toward which it moves, and correspondingly expands or enlarges the othery This expanded compartmentl compartment. is reduced or collapsed and the other compartment enlarged when the swinging board moves in the reverse direction. Thechamber communicates at each side of the swing-` ing `board f with a port, e2, extendingfrom the bottom of the chamber vertically to a horizontal port, e4. Both the horizontal ports ei lead at the outer ends to the external atmosphere, and at the inner ends to a trunk, E. Valves XV control the communication between the inner ends of the ports et and thee trunk Fl, and Valves V control the communication between t-he outer ends of the ports e4 and the external atmosphere. The valves V Flexible materia-l fin-such,` for instance, as india-rubber cloth-is con-Y IOO communication with the trunk E and cnt off from the communication with the external atmosphere. The trunk E communicates with the equalizer B.

The valve-rod U is connected with a lever, U5, shown as fnlcrunied to one of the fixed boards of the chamber. The valve-rod passes through this lever, and has around it helical springs, one on each side ofthe lever, and between the latter and a shoulder or collar on the rod. vWhen the lever is rocked, itwill shift the valve-rod; but, owing,` to the presence of the springs, it will operate the valverod with a yielding action, and consequently bring the valves which are to be closed to their seats without strainino. The lever U of each chamber is operated by a cam, K, on the shaft D of the motor. Vhen the motor consists of two chambers F, the shaft D will have two cranked set at right angles to each other and connected by pitinan-rods M with the movable boards f of the chambers F.

What I claim as my invention, and desire to secure by Letters Patent, is-
